The water supply for communities in the Canadian province of Saskatchewan is threatened by an oil spill that dumped an estimated 66,000 gallons of heavy oil, along with natural gas used to dilute it, into a major river.
The pipeline that broke is owned by Husky Energy Inc. The site of last Thursday's leak is within 1,000 feet of the North Saskatchewan River.
The central Saskatchewan town of North Battleford, which gets its water from the river, shut off its river intake last week and switched to groundwater, according to Reuters.
By far the largest community affected so far is the city of Prince Albert, which has a population of about 35,000 people. On Monday, officials there announced they had shut down the city's water treatment plant after the oil slick arrived in town. The CBC reports the city has enough water stored to last 48 hours, and officials are urging residents to limit water use to stretch that until the end of the week, which will buy time to get a backup system running.
Managers for the province's public works department are working to lay an 18-mile temporary water pipeline to supply the city with water from another source, the South Saskatchewan River.
The Globe and Mail reports authorities say they have recovered 40 percent of the spilled liquid so far.
The paper reports:
"In a telephone conference with reporters, officials from the province of Saskatchewan said they had built five booms to contain the spill and were working with Husky and the federal government on a cleanup plan. ... "Husky said the cleanup at the site of the leak had been completed, although neither it nor the province gave a time line for resolving the issue entirely. "The company also said three birds had been 'impacted' by the spill and that one died."
Despite the severity of the spill, and its widespread effects on people living downstream, the premier of Saskatchewan defended pipelines as the safest way to move oil over land, reported The Canadian Press wire service.
Premier Brad Wall told the wire service, "The facts remain that if we're not moving by a pipeline, it's going to move ... (by rail). We know that rail is actually more susceptible to spills and spills are often more intense."
The neighboring province of Alberta is considering pipeline options to bring crude oil from its tar sands to ocean ports, after a cross-border proposal that would have run through the U.S. to the Gulf of Mexico was shut down by the U.S. government.
